The exsting graph regularization nonnegative matrix factorization (GNMF) method still has some shortcomings: The GNMF algorithm does not consider the low-rank structure of data. In the GNMF algorithm, the Laplacian graph uses the K-nearest neighbor (KNN) method, and the KNN method cannot always obtain the optimal diagram, which makes the performance of the GNMF algorithm not optimal. For this reason, we propose an algorithm called nonnegative low-rank matrix factorization with adaptive graph neighbors (NLMFAN). On the one hand, by introducing low-rank constraints, NLMFAN can obtain the effective low-rank structure of the original dataset. On the other hand, a method for adaptively solving the similarity matrix is designed to construct the graph. This implies that the structure of the graph and the results of the matrix decomposition are integrated into an integrated framework so that the similarity of the nodes in the graph is automatically learned from the data. In addition, an effective algorithm for solving NLMFAN is given, and experiments on a variety of datasets verify the effectiveness of the algorithm.
